“…It has been suggested that near-infrared light penetrates deeper into the cortex in infants than adults, because infant brains contain less myelinated and less reflective white matter (Fukui et al, 2003). Therefore, the 20 mm distance between each emitter and detector probes pair used in this study was able to capture cerebral activity in relatively deeper regions of infant PFC, around 20~35 mm from the scalp-skin surface (Imafuku et al, 2014). …”

“…Converging evidence from functional neuroimaging studies suggests that the medial prefrontal cortex (MPFC) plays a pivotal role in social cognition, especially self-related information processing, not only in adults, but also in young infants (Kampe et al, 2003; Amodio and Frith, 2006; Northoff et al, 2006; Andrews-Hanna et al, 2010; Grossmann, 2013; Imafuku et al, 2014). Interestingly, neural activity of dorsal MPFC (DMPFC) and its peripheral areas has been shown to increase in tasks involving self-referential attention, and to decrease in tasks involving externally focused attention (Gusnard and Raichle, 2001).…”

“…To elucidate whether the aforementioned dynamic function of PFC has already emerged at this early age and to shed light on the functional development of primitive DMN, we designed two distinct sets of experiments. The first experiment, published in a previous report, focused on self-referential tasks and found increased hemodynamic responses in the DMPFC in 6-month-old infants in response to self-name calling (Imafuku et al, 2014). …”

The present study used functional near-infrared spectroscopy (fNIRS) to measure 5- to 6-month-old infants’ hemodynamic response in the prefrontal cortex (PFC) to visual stimuli differing in saliency and social value. Nineteen Japanese 5- to 6-month-old infants watched video clips of Peek-a-Boo (social signal) performed by an anime character (AC) or a human, and hand movements without social signal performed by an AC. The PFC activity of infants was measured by 22-channel fNIRS, while behaviors including looking time were recorded simultaneously. NIRS data showed that infants’ hemodynamic responses in the PFC generally decreased due to these stimuli, and the decrease was most prominent in the frontopolar (FP), covering medial PFC (MPFC), when infants were viewing Peek-a-Boo performed by an AC. Moreover, the decrease was more pronounced in the dorsolateral PFC (DLPFC) when infants were viewing Peek-a-Boo performed by an AC than by a human. Accordingly, behavioral data revealed significantly longer looking times when Peek-a-Boo was performed by an AC than by a human. No significant difference between Peek-a-Boo and non-Peek-a-Boo conditions was observed in either measure. These findings indicate that infants at this age may prefer stimuli with more salient features, which may be more effective in attracting their attentions. In conjunction with our previous findings on responses to self-name calling in infants of similar age, we hypothesize that the dynamic function of the MPFC and its vicinity (as part of default mode network (DMN): enhanced by self-focused stimuli, attenuated by externally focused stimuli), which is consistently observed in adults, may have already emerged in 5- to 6-month-old infants.

“…Since Moray's pioneering work, a large number of studies have shown robust support for the preferential processing of own-name stimuli, even in 6-month old infants (Imafuku et al, 2014). The exact relation of the phenomenon to attention, however, is controversial.…”

Although there is strong evidence that human decision-making is frequently self-biased, it remains unclear whether self-biases mediate attention. Here we review evidence on the relations between self-bias effects in decision-making and attention. We ask: Does self-related information capture attention? Do self-biases modulate pre-attentive processes or do they depend on attentional resources being available? We review work on (1) own-name effects, (2) own-face effects, and (3) self-biases in associative matching. We argue that self-related information does have a differential impact on the allocation of attention and that it can alter the saliency of a stimulus in a manner that mimics the effects of perceptual-saliency. However, there is also evidence that self-biases depend on the availability of attentional resources and attentional expectancies for upcoming stimuli. We propose a new processing framework, the Self-Attention Network (SAN), in which neural circuits responding to self-related stimuli interact with circuits supporting attentional control, to determine our emergent behavior. We also discuss how these-bias effects may extend beyond the self to be modulated by the broader social context-for example, by cultural experience, by an in-group as opposed to an out-group stimulus, and by whether we are engaged in joint actions. Self-biases on attention are modulated by social context.

“…Near-infrared spectroscopy (8) and EEG (9) studies examining responses to mother's voice have focused on young children (≤6 mo old) and have found increased neural activity for mother's voice compared to female control voices; however, the methods used in these studies are unable to provide detailed information about the brain areas and functional circuits underlying the perception of mother's voice. Therefore, a critical question remains: What are the neural representations of a biologically salient vocal source in a child's brain?…”

The human voice is a critical social cue, and listeners are extremely sensitive to the voices in their environment. One of the most salient voices in a child's life is mother's voice: Infants discriminate their mother's voice from the first days of life, and this stimulus is associated with guiding emotional and social function during development. Little is known regarding the functional circuits that are selectively engaged in children by biologically salient voices such as mother's voice or whether this brain activity is related to children's social communication abilities. We used functional MRI to measure brain activity in 24 healthy children (mean age, 10.2 y) while they attended to brief (<1 s) nonsense words produced by their biological mother and two female control voices and explored relationships between speech-evoked neural activity and social function. Compared to female control voices, mother's voice elicited greater activity in primary auditory regions in the midbrain and cortex; voice-selective superior temporal sulcus (STS); the amygdala, which is crucial for processing of affect; nucleus accumbens and orbitofrontal cortex of the reward circuit; anterior insula and cingulate of the salience network; and a subregion of fusiform gyrus associated with face perception. The strength of brain connectivity between voice-selective STS and reward, affective, salience, memory, and face-processing regions during mother's voice perception predicted social communication skills. Our findings provide a novel neurobiological template for investigation of typical social development as well as clinical disorders, such as autism, in which perception of biologically and socially salient voices may be impaired.
